How should teams build visibility before automating NHI controls?

TL;DR: Elastic’s blog describes a four-stage NHI programme built around asset inventory, shared best practices, dashboards, and automation, with a strong emphasis on owner engagement and continuous control monitoring. The lesson is that NHI governance fails when teams treat discovery, communication, and enforcement as separate problems rather than one operating model.

NHIMG editorial — based on research published by Entro Security.

By the numbers:

• 91% of former employee tokens remain active after offboarding, leaving organisations vulnerable to potential security breaches.

Questions worth separating out

Q: How should teams start governing non-human identities at scale?

A: Start with inventory, ownership, and lifecycle status before trying to optimise policy.

Q: When does automation help NHI security more than manual review?

A: Automation helps most when the organisation has high identity volume, repeated remediation patterns, and clear policy rules.

Q: What is the difference between NHI visibility and NHI governance?

A: Visibility shows what identities exist, where they live, and how they behave.

Practitioner guidance

• Build a governed NHI inventory Track every service account, token, API key, certificate, and workload identity with ownership, platform, environment, and last-used context.
• Prioritise stale and unused identities first Start remediation with NHIs that have no expiration date, no recent use, or unclear ownership because those identities create the highest low-effort exposure.
• Route remediation to identity owners Assign alerts to the team that created or operates the workload so security does not become the permanent cleanup function.

The better pattern is to treat lifecycle control as part of engineering flow, with inventory, review, and remediation connected from the start?
